摘要:
A method of recording an MPEG compliant transport stream selected by a user on a storage media. The method comprising: receiving the transport stream, the transport stream comprising transport stream packets; removing stuffing bytes from each transport stream packet in the transport stream containing stuffing bytes; recording all transport stream packets on the storage media; and recording an entry in a program information file on the storage media indicating that stuffing bytes were removed from the transport stream.

The invention relates to a system for recording a signal. A recorder (200) comprises a receiver (201) for receiving a source signal (101) having associated first play time information such as a Normal Play Time timeline. The receiver (200) is coupled to a recording controller (203) which generates a recorded signal (301) from the source signal (101). The recorded signal (301) comprises a recording discontinuity with respect to the source signal (101) caused by for example the recording being paused in a time interval. The recording controller (203) is coupled to a storage medium (205). The recorder (200) further comprises a time processor (209) for generating second time information for the recorded signal (301) in response to the first play time information and the recording discontinuity. The second time information may for example be a compensated NPT timeline or event descriptors or stream events having time indications modified to correspond to the recorded signal (301).
摘要:
A method (1) of transmitting interactive television, whereby interactive television applications are transmitted inside application-modules. These modules are transmitted in a broadcast stream. Recording systems cannot decide which modules are to be recorded. Therefore storage related information of said modules is signalled in the broadcast stream. Module identification information related is implemented in the Application Information Table (AIT) and/or in the Download Information Indication (DII) message. Thus information is included in the broadcast stream concerning categories stating whether application modules are mandatory, optional or forbidden to record. Alternatively properties of a module are chosen from Code/Data/Both and/or Fixed/Variable. Recording systems use this information do decide if application modules are to be recorded or disregarded. Alternatively, application module identification information is transmitted in said broadcast stream. A module identification number is used to avoid multiple recordings. Application modules having the same category are preferably grouped together.

An interactive television system includes a partial font generator (38) which generates a character font file of only those fonts used by a given application program for text display. The partial font file contains the language character fonts utilized by the application program, but less than the complete character set of the language. The partial font file thus requires less time or bandwidth to transmit in the allotted transmit intervals. The partial font file may be generated by a manual process, or by an automated analysis of the fonts used by application program.
摘要:
A method and device for storing an interactive television program for playback at a later point in time, wherein said interactive television program comprises at least one interactive television application. The applications are transmitted inside modules (11, 12) through a data carousel (2) within a transport stream (20). The method comprises receiving the transport stream, parsing the stream for application modules and storing them as a storage stream on a storage medium (31). The storage stream is stored separate from said transport stream (20). The data or object carousel is recorded outside the Transport Stream and recorded like a stream, preferably as a single file. This file is a sequence of modules with some header information preceding the modules making playback faster as the information needed to obtain the objects from a module is located directly in the header of that module. Furthermore, the solution according to the invention solution is platform independent.

An optical disk, optical disk player and optical disk playing method are disclosed, wherein the optical disk is used to play in coordination with the downloaded contents. The optical disk has a public key used to verify whether the downloaded content is authenticated. The optical disk player comprises a reading-out means, a network interface and a verifying module, in which the reading-out means is used to read-out the content and the public key of the optical disk; the network interface is used to receive the downloaded content; and the verifying module is used to verify whether the downloaded content is authenticated according to the public key read-out from the optical disk. The optical disk playing method consists of reading-out the content and the public key of the optical disk, downloading the content, then verifying the downloaded content according to the public key read-out from the optical disk, in order to confirm whether the downloaded content is authenticated.

A method (6,7) and device (8) for recording and/or reproducing interactive television data via a digital interface (45), wherein said data is transmit inside modules through a DSMCC data/object carousel (2) with a first bandwidth. The method comprises the steps of calculating repetition rates of said modules in said DSMCC carousel (2), recording said modules, together with said repetition rates of said modules, from said digital interface (45) to a storage medium of a recording device, and/or playing back said data inside modules through a second DSMCC Data/Object Carousel (4) over said digital interface (45) and from a storage medium, preferably using the complete available bandwidth of said digital interface for said DSMCC Data/Object Carousel (4), wherein said modules are preferably re-inserted over the digital interface (45), such as into a Transport Stream, at a repetition rate being stored together with said modules on said storage medium.
摘要:
An apparatus (270) and method is disclosed for preventing a viewer from switching from a channel when an advertisement is being displayed on the channel. The apparatus (270) and method comprises an advertisement controller (270) in a video playback device (150) that (1) prevents a viewer of a direct (non-recorded) broadcast from switching channels when an advertisement is displayed, and (2) prevents a viewer of a recorded program from fast forwarding the recorded program in order to skip past advertisements that were recorded with the program. A viewer may either watch the advertisements or pay a fee in order to be able to change channels or fast forward when the advertisements are being displayed.
摘要:
A first content is received and presented to a user on a television (TV) platform (16). A second content is also received and presented concurrently to the user. In an interactive TV platform (16), a user selects the second content. In one aspect, the first content is advertising content (40) and the second content is information content (46), electronic mail content (42), downloadable file content (44), or program content (32, 34, 36, 38). In another aspect, the first content is program content (32, 34, 36, 38) and the second content is one of information content (46), electronic mail content (42), advertising content (40), and downloadable file content (44).
